A glimpse of @iowastatepatrol Trooper Moore on Interstate 80 in western Iowa last night! There is a reason the @NWSOmaha @NWSDesMoines and first responders warn in advance of these blizzard conditions and to STAY HOME. First responders had to rescue many and take to shelters!



There is a massive amount of dust being picked up by strong winds over KS, OK, TX, CO, NM currently and can be seen here in light brown. That dust will arrive over Iowa this evening. Any precipitation will use this dust as nuclei so expect dirt on your cars in the morning #iawx



Thanks so much to my old friend Rod Donovan at the US National Weather Service Des Moines Iowa for hosting us for the evening shows ahead of tomorrow’s storms. Such a great partnership and we’re lucky to get to collaborate with these folks. #iawx @NWSDesMoines

The large dendrites have arrived in west Ames. The radar imagery is differential reflectivity, with the higher band showing the area of stellar dendrites. 33 degrees, though, so SLR is lower. @NWSDesMoines




The wind potential for Tue night/Wed is the strongest signal we have seen since 12/15/2021. The exact timing the rain/snow transition Tue night is less certain and will impact snow amounts but 1" per hour rates may occur at times. Significant travel impacts are very possible.

We are also currently accepting abstracts for #ssdrc2025 through Friday, February 28! To submit your abstract, please email it to Dr. William Gallus (wgallus@iastate.edu), and indicate whether you prefer an oral of poster presentation. #iawx
